面向无人机网络的属性代理签名方案

Attribute-based proxy signature scheme for unmanned aerial vehicle networks

为保护无人机网络中指挥机构发送给无人机的命令的完整性和认证性,需要使用数字签名对命令消息进行保护,该签名方案应保证无人机能及时收到签名,并且保护签名者的隐私。因此,提出了面向无人机网络的属性代理签名方案,并对其安全性进行了分析。所提方案在选择属性和选择消息攻击下具有存在的不可伪造性,而且能保护签名者的隐私。从计算开销和通信开销两方面对签名方案的效率进行了分析,并与其他相关签名方案进行了对比。结果表明,所提方案与其他方案在通信开销处于同一水平时具有更小的计算开销。

It is necessary to use digital signature scheme to protect integrity and authentication of commands sent by command agencies to unmanned aerial vehicle(UAV)in the UAV networks.Moreover,the signature scheme should ensure UAV can receive signature in time and protect privacy of signers.Therefore,an attribute-based proxy signature scheme for UAV networks was proposed and its security was analyzed.The proposed signature scheme has existential unforgeability under selective-attribute and chosen message attacks,and privacy of signers is protected.Its efficiency was analyzed in terms of computation costs and communication costs,and compared with other related signature schemes.The results indicate the proposed signature scheme has less computation costs when its communication costs are at the same level with other signature schemes.
